AIS Tester

AIS Tester is a test device operating on AIS1 (ch87B), AIS2(ch88B) and DSC(ch70) frequencies. The tester is designed under corresponding standards and recommendations as a tool of operation and installation tests of AIS units (Automatic Identification System). The tests’ volume complies with “Guidelines on annual testing of the AIS unit MSC.1/Circ.1252”.

AIS Tester completely corresponds to new requirement that is set out in IMO Resolution MSC.308(88) under new regulation 18.9 to Chapter V of SOLAS.

Tester does not use a GPS for synchronization. A proprietary TDMA slot-synchronizing algorithm is used which does not require a GPS 1pps. It uses RATDMA for generating VDL and interrogation messages. A Pilot Plug evaluation function and NMEA/RS422 terminal display of external sensor inputs are provided.

The input signal displaying on LCD from external sensors through the RS-422 port provides the control of “Pilot plug”.

Tester provides all measurements of testers of other manufacturer's such as AITS-R, Maritec, RSA and Futronic GMDSS/AIS Test Box, Futronic I/S, Denmark.

Tester’s features:

AIS Tester allows to:

- Poll, receive and check data from AIS transponders.
- Simulate AIS data transmissions, such as ship’s name, position, length, course, speed,
power and beam.
- Simulate AIS data transmissions, such as ship’s name, position, length, course, speed,
power and beam.
- Poll information on channel 70
- Simulate NMEA data transmissions.
